TOSHIB A Bi-CMOS OSHIBA Constant Cur ace Dri ver Currrent Interf Interface Driv TB62708N 16 Bit Constant Current LED Source Driver with Shift Register and Latch Functions Product Description: The TB62708N is specifically designed for LED display applications. The Bi-CMOS device has 16 Bi-polar constant current output source channels and includes CMOS shift register and latch functions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-90mA and is held constant across all 16 source outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs. TB62708N Features: • Current Source Device • 16 Constant Current Output Channels • Current Programmable from 5-90mA • 5V CMOS Compatible Inputs • 15MHz Max Clock Frequency (Cascade) SDIP30-P-400 Block Diagram: Company Headquarters 3 Northway Lane North Latham, New York 12110 Toll Free: 800.984.5337 Fax: 518.785.4725 California Sales Office: 950 South Coast Drive, Suite 265 Costa Mesa, California 92626 Toll Free: 800.984.5337 Web: www.marktechopto.com | Email: [email protected] Fax: 714.850.9314 For up-to-date product info visit our web site at www.marktechopto.com All specifications subject to change.
